Shareholders
3
Three shareholders are currently on record for Kalaris Therapeutics, Inc., reflecting the stock ledger kept by the company under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 2.2% — the largest recorded stake — followed by Fidelity Concord Street Trust-Fidelity Extended Market Index Fund at 0.3%; the remaining 1 shareholder shown holds smaller stakes.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
